Hi there!
If you have problems with the camera being unable to connect, the following information can help you.
1. Please check if the camera IP can be pinged.
2. Please check if the camera IP address is correct and whether it has been modified (such as receiving another IP address from the DHCP pool).
2.1. Set the camera's IP address to the fixed IP. On the same network segment of the router, such as the router's IP (192.168.1.1), the camera can be set to 192.168.1.254.
2.2. Accessing the IP camera using the IP address received from the DHCP Pool.
3. Check if the camera is plugged in.
4. Check for other hardware or cable failures.
